### Description

In Liferay Portal before 7.1 CE GA4, an XSS vulnerability exists in the SimpleCaptcha API when custom code passes unsanitized input into the "url" parameter of the JSP taglib call <liferay-ui:captcha url="<%= url %>" /> or <liferay-captcha:captcha url="<%= url %>" />. Liferay Portal out-of-the-box behavior with no customizations is not vulnerable.
